FAQ
Will this fit my truck?
This set fits 2006.5–2007 6.0L Power Stroke engines equipped with 20 mm alignment dowels. Verify dowel size by build date or with your cylinder heads.
What if my engine has 18 mm dowels?
Use the 18 mm-specific head set instead. Ford used 18 mm dowels from 2003–Jan 11, 2006, and 20 mm from Jan 12, 2006+.
Are head bolts or studs included?
No—purchase head bolts or studs separately. Inner-row head bolts are also sold separately.
Are the gaskets MLS and coated?
Yes—this kit uses MLS head gaskets with a Black Diamond coating for durability and sealing performance.
